HAND-STAMP.

Specification of Letters Patent.

Patented June 8, 1915.

Application filedNovember 11, I912. Serial-No. 730,583.

'To all whom it may concern:

Be it known that I, WILLIAM H. DODSON, a citizen of the United States,residing in the city of New York, borough of Manhattan, county and Stateof New York, have invented certain new and useful Improvements inHand-Stamps, of which the following is a full, clear, and exactspecification. I I

My invention re ates to certain new and useful improvements in handstamps and has for its object, the production of a'stamp having a highdegree of efficiency and durability, and especie 11y to the provision ofmeans for holding inking-pad normally out of contact with the stampingdie, and for permitting its contact therewith only m0- mentarily andjust before the stamping operationis performed.

One form ofmy invention'is illustrated in the accompanying drawingsforming part of this application and in these drawings,fFigure 1 is asectional view of a hand stamp, showing the parts in their normalposition, and Fig. 2 is a side elevation in full line. As will bereadily understood from these drawings, my invention is applicable toall kinds of stamping apparatus,

but for convenience of illustration I have shown it in connection with ahand stamp of well known character, wherein the stamp element 'orprinting head is normally held face upward, and by the depression of thehandle is caused to reverse its position before making the impression.The reversing mechanism is not shown, as it forms no part of myinvention and is of well known character.

Describing my invention and referring to the drawings the numeral 1indicates a printing head or stamp member of well known character. Thisprinting head is mounted in a frame 2, which is provided with aninverted recess, in which the inking-pad 3, is normally housed, said padhaving lugs 3 formed thereon and positioned within the apertures 3 Theframe 2 is provided with a cylindrical member 4 upon which the operatinghandle reciprocates, and within cylinder 4 a smaller cylinder 5 isprovided, the lower end of which is permanently connected to aninking-pad where it passes through the aperture 6 in the frame. A thirdcylinder 7, of a diameter to fit snugly over the cylinder 4, and whichslides easily thereon,

is also employed and a handle 8, having an internal bore sufiiciently'large to allow it to slide over the cylinder 7, is also provided. Theupper end of the smaller cylinder 5 is contracted 10, having a head 11,

as at 9 and through an aperture in this s bears upon the top of theframe within the i cylinder 4 and surrounding the cylinder 5, and itsupper end bearing against the contracted upper end of the cylinder 7.Spring 15 is located with its lower end bearing upon the upper end ofthe sleeve 5, and its upper end upon the underside of the washer 12,while the spring 16 has its lower end bearing upon'the upper side of theWasher 12, and its upper end against the underside of the recess wall inthe handle 8.

The operation of my device will be readilyl understood from theforegoing and from an examination of the drawings. As shown in Fig. 1,the parts are in normal position, the printing head upturned and theinkingpad slightly above the same but out of contact with it. Uponapplying downward pressure to the handle, the spring 16, which iscomparatively weak, is compressed, and on continuing the pressure on thehandle, the rod 10 is forced downwardly and carries with it theinking-pad which is forced against the printing head with a yieldingpressure, which is regulated by the strength of the spring 15.

On continuing the downward movement of the handle, the arms 17, whichcontrol the printing head reversing mechanism, are forced downward, thuswithdrawing the printing head from the inking-pad, the further downwardmovement of the inking pad being limited by the lugs 8 abutting thelower edges of the apertures 3 and causing an impression to be made, thedownward pressure of the handle being resisted by the tension of allthree springs, which however is not excessive, but is sufficient toaccomplish the purpose.

It is obvious that many modifications and changes may be made in myinvention, without departing from the essential features containedtherein, and I do not wish to limit myself to the exact detailsdescribed, but

What I claim as new herein and desire I to secure by Letters Patent is:

1. A stamping apparatus comprising a a movable printing head mountedhead and means for forcing the inking-pad into contact with saidprinting head and further operable in the same direction for causing theprinting head to be brought into contact with the object upon which theimpression is to be made by a single operation. V

2. A hand stamp comprising a frame, a movable printing head mountedtherein, an inking pad mounted in proximity to said printing headmovable in the plane of movement of said printing head and normally outof contact therewith, and means initially operable to move said inkingpad into contact with said printing head, the continued operation ofsaid means in the same direction actuating said printing head.

3. A hand stamp comprising a frame, a movable printing head mountedtherein, an inking padmovable in the plane of movement of said printinghead and normally 3 out of contact with said printing head, a

handle operatively connected to said printing head and to said inkingpad, and means whereby the initial movement of said handle will bringsaid inking pad into contact with said printing head, and whereby theCopies of this patent may be obtained for in inking pad movable in aninking-pad movable in'the plane continued movement of said handle in thesame plane will operate saidv printing head.

4. A. hand stamp comprising a frame, a movable printing head mountedtherein, an

the plane of movementof said printing head and normally out of contactwith said printing head,a handle operatively connected to said printinghead and to said printing pad, means whereby the initial movement ofsaid handle will bring said inking pad into contact with said printinghead, and whereby the continued movement of said handle in the sameplane will operate said printing head, and automatic means for returningthe parts to their normal positions.

5. A hand stamp comprising a supporting frame, a movable reversibleprinting head mounted therein, an inking pad of approximately the samearea as said printing head, movably mounted within said frame, andnormally out of contact with said printing head, a handle operativelyconnected to said printing headand to said inkingpad, f

means whereby the initial movement of said handle will'bring said inkingpad into contact with said-printing head,fand whereby the continuedmovement of said handle in the same direction will operatesaid print inghead, and means for returning the parts 7 to their normal positions. v M

In witness whereof I have hereunto set my hand in the presence of twosubscribing Witnesses. r
